Optical & Photonic

Keysight offers a wide-range of innovative test and measurement solutions to accelerate the progress of next-generation intelligent optical networks.

Keysight's mission in the optical market is to shorten time-to-market and reduce cost-of-test for customers in R&D and manufacturing, as well as enable new technologies which include innovative optical components, network elements & systems, and all-optical fiber networks.

This application note is for R&D designers and engineers working on high-speed digital designs. It addresses jitter measurements in digital circuits, how the different measurement techniques are best applied, and how these decisions may change as the data rates increase.

There is no simple way to decide how much oscilloscope bandwidth you will need. Scope vendors promote a “fifth harmonic” rule of thumb. They suggest you purchase a scope with sufficient bandwidth to capture the fifth harmonic of your signals.

A transmitter sends a serial signal over a transmission channel (examples: backplane, cable) to a receiver. As the signal rate increases, the channel the signal travels through distorts the signal at the receiver.

The 15431A is a filter set for the 81150A. It generates the random jitter profile for testing PCI Express 2.0 receivers, to be used in conjunction with the N4903A. This fact sheet explains the upgrade.
